Abstract

Provides a brief summary of an OCLC funded project 'Identifying barriers to effective subject access in library catalogues'. The study investigated the probability that a skilled catalogue user would retrieve 'the best' materials on some subject, and if they were unable to do so, to determine how this could be improved. The transformation of the card catalogue onto an online database has not improved subject access. Offers a view of research in the context of the education and research roles of the library and information science educator. Discusses the university research environment, teaching students research skills and OCLC

Abstract

Identifies and characterizes the knowledge used by experienced librarians while searching for subject information in online catalogues. 10 experienced librarians performed the same set of 6 subject searches in an online catalogue. Investigates the knowledge used to solve retrieval problems. This knowledge presents expertise in the use of the catalogue. Data were collected through the use of think aloud protocols, transaction logs and structured interviews. Knowledge was defined as knowledge objects (factual knowledge), knowledge of events (experimental knowlegde), knowledge of performance (process knowledge), and metaknowledge. Metaknowledge is the sense of whole derived from the integration of factual, process, and experimental knowledge about the search and the conditions under which it is performed. Focuses on metaknowledge. For evidence of metaknowledge the data were examined for explanations that participants gave for their actions and observations, and for ways that participants evaluated their own progress during the process of searching. Reasons and explanations given by searchers were related to all phases of the library information retrieval process from the user's receipt of material to policies for collection development, and not just events directly related to the performance of a particular search task

Abstract

Discusses established approaches to subject access using subject headings (such as LCSH), and the demands for improved subject access associated with the widespread availability of OPACs and the evidence of problems experienced by catalogue users in subject searching

Abstract

Explores the question of whether academic libraries keep up with the changes in the LCSH system. Analysis of the handling of 15 subject headings in 50 academic library catalogues available via the Internet found that libraries are not consistently maintaining subject authority control, or making syndetic references and scope notes in their catalogues. Discusses the results from the perspective of the libraries' performance, performance on the headings overall, performance on references, performance on the type of change made to the headings,a nd performance within 3 widely used onlien catalogue systems (DRA, INNOPAC and NOTIS). Discusses the implications of the findings in relationship to expressions of dissatisfaction with the effectiveness of subject cataloguing expressed by discussion groups on the Internet
